Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed Nvmhl 3, 1905. Serial No. 285,724.

To all whom it may concern:

Beit known that I, DYcxE H. REIMERS, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illi-` speed thereof, and While it is more especiall intended to be employed in connection wit and for the transmiss1on of power in driving automobiles, yet it is applicable for the transmission of power for other purposes; and it consistsin certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinanism whereby the power is transmitted byV after more fully set forth and specifically claimed.

The principal object of the invention is to providesim le and efficient means for transmitting an directly applying power to the rear axle of an automobile or the driven shaft of a machine.

Another object of the'invention is to furnish an improved power-transmittin mechthe frictional contact of certain parts vthereof, which shall be so constructed as to utilize the pressure or power employed to hold theI frictional members in contact, (which ordinarily produces what is termed an end thrust,) so that the more pressure or .power employed will serve to increase the friction on each side of the driven wheel, thereby avoiding any end thrust or lateral movement of said wheeland also preventing the bearing thereof becoming worn.

.Other objects and advantages of the inven-l tion will bedisclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now'proceed to describe it, referring to the accompanying drawings, in whichv Figure 1 is a view in side elevation of a power-transmitting 'mechanism 'embodying the invention, showing a portion of the supporting-frame on which it is mounted. Flg.

2 is a plan viewl thereof, partly in elevation and partly in section, but showing a ortion of the supporting-frame removed. 3 is a rear end view in elevation, showing t e p0- sitions the parts will occupy when operating to drive. the machine forwardly or in one direction. Fig.- 4 is a diagrammatic view of Vthe friction elements, illustrating them in the positions they will occupy when the movement of the machine is reversed. Fig. 5 is an enlarged perspective view of one of the brackets which support the rear ends of the shafts on which certain frictionalI members are movably mounted; and Fig. 6 isa fragmental face view of the driven disk, showing a modification in its construction.

Like numerals of reference refer to corresponding parts throughout the different views of the drawings. I

The supporting-frame for the mechanism are counterparts of one another, each of which consists of a collar 10, loosely mounted at a suitable distance apart on Ithe rear axle 11 of the automobile when the mechanism is employed for driving the same, and a num.- ber of rods or pieces of pipe which are fitted at their inner ends in socketed projections 12 V on each ofthe said collars. As is clearly shown in Fig. 1 of the drawings, these pipes, rods, or bars arearranged so that two of them, 13 and 14, will extend forwardly from the axle 11, while the Vother two, 15 and 16, extend rearwardly Ifrom the rear axle. It-

`will also be observed and understood that the rod 13 of each of the portions of the supporting-frame extends upwardly andforwardly, while the ro'd 15 of each of said portions extends upwardly and rearwardly, while lthe rod 14 .extends downwardly and forwardly and the rod 16 downwardly and rearwardly and then upwardly. These rods or pieces of pipe may be secured to any suitable support, such as beams 17 or the bed-frame of the automobile. The rods 13 and 15 of each of the IOO portions of the supporting-frame are united means of a truss' 18, to eachof which is 'the axle 11 between the colchine.

-on the shafts 26 when it is desired to change may be covered or provided on its faces with l fiber or other suitable frictional material. Horizontally journaled in parallelism with the axle or shaft 11 and near the same is the main or driving shaft 21, which may be supported by means of brackets 22, secured to earns 17 or other suitable supports. The shaft 21 is connected in any suitable manner to an engine (not shown) and has loosely mounted on its middle portion two boxes or brackets 23, each of which is provided with a forwardly-extending projection 24, having in its free end a horizontall -elongated opening 25 for the, reception o the rear ends of the shafts 26, on each of which shafts is mounted a friction-disk 27, which will be herein designated as the intermediate direct-drive disks. Each of these disks is provided with a grooved hub 28 to engage the lower ends of the yokes 19, which, as before stated, are pivotally secured at their upper ends to a part of the supporting-framefor example, the trusses 18dand said yokes may be operated by means of a rod 29, so that the disks 27 may be slid back and forth the rate of speed of the machine. The fron"L end of each of the shafts 26 is pivotally secured between lugs 30 on each of the collars 10, so that said shafts may have a slight lateral movement within the openings 25 of the boxes or lbrackets 23 therefor'. Just above each of the collars 10 the rods 13 and 15 are connected together by means of a bar 31, on which is fulcrumed a lever-shaft 32, on the rear end of each of which is journaled a small friction disk or roller 33, used for reversing the movement of the machine and which will be called-the intermediate reversing disks or rollers. The front end of each of the lever-shafts 32 is pivotally connected to one of the shorter arms 34l of a bell-crank lever, which is fulcrumed on a suitable support 35 on the front part of the supporting -frame As shown, Fig. 2,` the be l-crank lever is provided with two short arms which diverge from its fulcrum, and said -lever has connected to its longer arm 36 an operating-rod 37, which is employed to lower the intermediate reversing-disks 33 to the (positions shown in Fig. 4 when'it is desire to reverse the movement of the manear the outer surface of each of the intermediate direct-drive disks 27 is a directdrive disk which consists of a disk 38, rigidly secured on said shaft, and a disk'39, which is slidably mounted on the drivingshaft. Each of the disks 38 is provided near its periphery with a series of openings 40, through which are extended bars 41, which are pivotally secured at their outer ends to lugs on the disk 39 and have their other ends pivotally secured to the outer ends of levers Mounted on the driving-shaft 21 l 42, which are fulcrumed on the hub of the disk 39 and have their inner ends passing through suitable openings 43 in the disk 38 and pivotally 4secured to the disk 39, as is clearly shown in Fig. 2 of the drawings. Slidably mounted on the driving-shaft 21 outwardly from each of the hubs of the disks 38 is a cone-sleeve 44, which sleeves are united by means of a yoke v45, which is fulcrumed, as at 46 and 47, (see Fig. 2,) and has connected to one of its sides an operating-rod 48, by means of which the sleeves may be slid toward each other, so as to move the inner ends of the bars 41 andl levers 42 outwardly, each other and against the disks 27, which in turn are pressed against the driven disk 2O with a uniform pressure, thus neutralizing or avoiding any lateral movement of the driven disk, or what is ordinarily termed the end thrust thereof. It is`also apparent that by the arrangement ofthe bars 41 and levers 42, which actuate the disks 39, the pressure on said disks will be so distributed as to avoid the lateral movement thereof, as well as a similar movement of the disks 38, wnich,

as before stated, are rigidly secured on the driving-shaft.

When it is desired to drive the machine in a forwardly direction, the operating-rod 48 should be moved in the proper direction to cause the sleeves 44 to bei moved toward each other, which operation, through the instrumentality of the bars 41 and levers 42,will slide the disks 38 on the shaft 21 toward each other and against the intermediate directdrive disks 27 which in turn will be forced against the driven disk 20, thereby causing the same to be rotated, the speed of which may be regulated or controlled by moving the yokes 19 by means of the operating-rods t29 in the proper direction,'wh.icn yokes, as

before stated, engage the hubs of the disks 27, so as to slide them back and forth on the shafts 26, which carry said disks. When it is desired to reverse the movement of the machine, the operating-rod 37 may be moved in the proper direction to lowerthe inner ends of the lever-shafts 32, which carry the intermediate reversing-disks 33, so that the same will be brought into contact *with the disks 27 on their surfaces adjacent to the driven disk 20, which operation-Will producev the reverse movement of the driven disk as Well as of the machine.

In Fig. 6 of the drawings I have shown a modified form 11a of the driven disk, which consists in providing each of its faces with a series of indentations or cups 49, which are 'preferably arranged in concentric circles or rows and are preferably elongated, as shown. These depressions or indentations are employed to augment thefriction incident to the intermediate disksand the driven disk, for it is apparent that as the intermediate disks contact with the faces of the driven ITO disk over the indentations and pass from the same an exhaust of suction will take place, thus preventing the disks slipping. It will be understood that the intermediate disks, as well as the disks 39, may be provided Withfiber or other suitable frictional material on their contacting surfaces and that the driven disk 2O may or may not be provided with such material. To support the brackets or boxes 23, rods 50, secured at one of theirends to the supporting-frame and at their other ends to t e lugs 5l on said boxes, are

l employed.

While I have shown and above described the mechanism with the driving power applied to the shaft 21, yet it is evident that the shaft 11 may be connected to the engine or ,source of power, in which event the disk 2,0

would become the driving-disk and the disks mounted on the shaft 21-wouldbecome the driven disks.

Having thus fully described my invention, what I claim as new, and desire to secure by ported, an intermediate direct-drive diskl slidably mounted on each of said longitudi.

nal shafts, and means to slide said intermediate disks back and forth on their shafts,

,substantially as described.
